Title: Field-effect transistor
Inventor: YOSHIDA JIRO
IPC: H01L29/778
Filed: 1984-10-25
Abstract: PURPOSE:To prevent the creeping of currents to a substrate by forming a non- doped semiconductor layer having small electronic affinity up to the position shallower than the depth of a low resistance region under source-drain electrodes. CONSTITUTION:A non-doped AlGaAs layer 12 having small electronic affinity is grown on a semi-insulating substrate 11 in an epitaxial manner, and a non- doped GaAs layer 13 as a channel layer is formed onto the layer 12. An AlGaAs layer 14 containing an N type impurity is shaped. Metals as source-drain electrodes are applied and thermally treated, and ally layers 17 having low resistance are prepared under these electrodes 15, 16. The layers 17 are made to reach the layer 12 so as to be excellently brought into ohmic-contact with an electron group in the channel layer. According to such constitution, superior current saturation characteristics and current interrupting characteristics are obtained even through a channel is shortened.

Title: Abrasive composition for chemical-mechanical polishing
Inventor: KIDO TAKANORI
IPC: B24B37/00
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain an abrasive composition for chemical-mechanical polishing which has such a high polishing rate as to permit effective polishing and can give a finished surface reduced in the formation of corrosion specks and in dishing by mixing a carboxylic acid with an oxidizing agent and water and adjusting the pH of the resulting mixture with an alkali. SOLUTION: This composition is obtained by mixing a carboxylic acid with an oxidizing agent and water and adjusting the pH of the resulting mixture to 5-0. In the composition, it is desirable that the molecular weight of the carboxylic acid is 100-300. When it is below 100, the polishing rate is so low that there is a risk of forming corrosion specks. When it is above 300, the acid is scarcely water-soluble, so that there is the prossibility of failing in attaining the effects of improving a polishing rate and of suppressing the formation of corrosion specks. The oxidizing agent contained has the effects of accelerating the oxidation of a metal and of improving a polishing rate. Adjusting the pH to 5-9 with an alkali enables to suppress the active dissolution of a wiring material, prevent the formation of corrosion specks, and attain a high polishing rate.  The composition is desirably used in the production of semiconductor devices.
